Child Thread: Survey of registry namespace designs for Cargo and Crates.io

kornel:

The Homebrew core tap is curated, which is reassuring it won't suddenly spring drive-by typosquatted packages

I feel this is a big part of what makes this design of implicit merging work. Along with the fact that taps generally are for adding packages that don't exist, so that in general brew install $package is almost always going to install it from where you expect, or give a "not found" error if you forgot to add the tap.
